2 Claims. (Cl. 2265-107) 1 This invention relates to liquid dispensersand more particularly to dispensers of carbonated, gaseous or chargedliquids.

It is an object of this invention to provide a liquid dispenser havingintermediate metering" chambers positioned between a liquidc'ontainer'and dispensing valves, separating and dispensing a measuredamount of liquid from the liquid container. i

' It is a further object of this invention to provide a valve operatingmechanism, controlled in volume primarily by the increasing weight ofthe liquid being dispensed 'into a vessel wherein the vessel is incommunication with the valve operating mechanism.

It is a still further object of this invention to retain a liquidreceiving vessel with a valve operating mechanism angular to the flow ofthe dispensed liquidiatits initial start reducing excessive foaming ofgaseous liquids entering the vessel. i

Further objects of this invention reside in the'r'natering chambereswherein a piston separates the chambers, and suitable brakes areassoeiatedwith the piston to reduce the liquid container pressure to thedispensing faucet.

of Fig. 3 showing the valve in mounted position on the the cylinder. i iFig. 5 is a side elevation taken through a cabinet illustrating theliquid dispenser and liquid container in working relationship to oneanother.

Fig. 6 is a side elevation partially brokenaway illustrating a modifiedand simple valve operating mechanism. A liquid dispenser embodying ourinvention comprises a body member 1, in the form of an upstanding spoutportion 2, a discharge outlet 4, a cavity 6, formed within the body 1,having a valve 8, and valve linkage 10, mounted within the cavity 6, thelinkage 10, being connected to a hinged, movable glass holder 12,extending outward and below the discharge outlet 4. Mounted below thecavity 6, andforming part of the valve 8, is a pair of metering chambers13 and 14, being in the form of a cylinder with a movable piston 16,separating the same with one of the metering chambers being incommunication with a pressurized liquid container 18, through the valve8, and the other chamber being in communication with the dischargeoutlet 4, through the valve 8, and by reversing the valve, the meteringchamber communications are reversed.

2,757,846 Fa tented Aug. 7, 1956 From the above brief description, itwill be noted that a gaseous liquid as beer or carbonated liquids isadmitted into one of the metering chambers under pressure from thecontainer 18, while the retained liquid in the other metering chamber isdischarged by the action of liquid pressure against the piston 16,completing one cycle of operation and by reversing the valve 8, theliquid in the first metering chamber is isolated from the container 18,

and discharged in the manner above described.

' Describing our invention in detail we provide the liquid container 18,being of a standard type and provided with an inlet pipe being connectedon one end to a suitable air compressor machine not shown in thedrawings to facilitate maintainingthe liquid container at a constantpressure preferably above the gas pressure of the liquid in thecontainer, a pipe 19, starting at the lower extremity of the container,connects the container 18, to the valve 8, and into the chamber 20, asillustrated in Fig. 3 of the drawings. The liquid then flows into theport 21, through the pipe 22, into the metering chamber 13 at 23,forcing the piston 16, to move within the cylinder, causing the liquidin the metering chamber 14, to flow through the pipe 24, into the port25, of the valve 8, and then directed into the port '26, by a recessedportion 27, forming a part of the movable valve portion 28, mountedwithin the chamber 20, of the valve 8.

Shown in Fig. l ofthe drawings, the port 26, of the valve 8, is incommunincation with port 29, forming part of the body member 1, anddirects the liquid flow to the discharge outlet 4. i As described above,the liquid flows into the chamber 13, of the cylindercausin'g the piston16, to move within the cylinder. The piston 16, is mounted centrally onthe shaft 30, which in turn is journ'aled within the cylinder end"pieces 31 and 32, and eXtends outward therefrom, suitable adjustablestop pieces 33 and 34, are secured to the outer ends of the shaft 30, tostop the movement of the piston 16, within the cylinder as' illustratedin. Fig. 3, the adjustable stop 33, contacting the end piece 31, allowsthe piston16, to move only a predetermined distance in the cylinder alsoallowing only a metered amount of liquid to enter the chamber 13, and asreadily seen, an equal amount of liquidwill be discharged from thechamber"14, through the discharge outlet 4,

To decrease and/or slow down the speed of travel of the piston Withinthe cylinder and thereby soften the flow of liquid from the dischargeoutlet 4, from the chamber 14, due to the liquid under pressure beingadmitted into the chamber 13, we provide shock absorbing brakemechanisms 34, positioned in the cylinder ends 31 and 32, and beingcomprised of one or moreround rubber rings 35, commonly trade-named as 0rings, the rings 35, snugly fit onto the shaft 30, and are nested into aretainer pocket 36, in the cylinder ends 31 and 32, a pressure plug 37,is threaded into the cylinder ends 31 and 32, abutting against the ringscompressing the same tightly into the pocket 36, and around the shaft30, causing a braking action against movement of the shaft 30, theamount of braking action to the shaft 30, being predetermined by theamount of compress applied to the rings proper. A further advantage ofthe above construction being the rings 35, form a leak-proof packinggland preventing leakage of liquid from the chambers 13 and 14.

It has been found, when dispensing gaseous liquids, excessive pressureswithin the liquid create foaming when the pressurized liquid is releasedinto the atmosphere, i. e. sparkling waters, refreshment drinks,bromides, and various chemical solutions. To soften the gaseousexpansion of the liquid when dispensing the same, I provide the chambers13 and 14, one of the said chambers receiving liquids from the source 18and the other to release liquids under controlled conditions to the dis-3 charge outlet 4 by using the inlet pressures into chamber 13 to movethe piston 16 forcing liquids in the chamber 14 through the outlet 4.

To reverse the direction of liquid flow to the chambers 13 and 14, themovable portion 28, is-moved within the chamber 20, of the valve8,opening port 25, to the chamber 20, allowing the liquid to enter the.chamber 14, and from chamber 13, the liquid is directed into port 38, bya recessed portion 39, and then through the outlet 4 via the outlet port29.

The movable valve portion 28, is operated by the valve stem 40,extending through thechamber 20, and fastened on its one end to thevalve operating linkage 10.

i of the link 46, will travel downward in the inclined slotto the aboveand when the glass is removed, the bearing In Figs. 1 and 2 of thedrawings we have illustrated the I valve operating linkage as beingcomprised of a holder 12, having a back portion 41, and a bottom 42,typical in construction toreceive -a common beverage glass 43, the upperportion of said holder-extends rearward in the form of an arm44,-being;hinged within the spout portion 2, at 45, a link 46, beinghinged to the outer end of the arm at 47, on its one end and its otherend is bearinged for reciprocal travel in the slotway 48, of the walkingbeam like lever 49, the action of which will be described later.

The walking beam 49, is fastened through its central portion to acountershaft 50, which in turn is bearinged within the cavity 6, a lever51, is also fastened to the countershaft 50, and is hinged on its outerend to a link 52, and the link 52, in turn being hinged to the valveoperating stem 40, of the valve 8, now therefore when the walking beam49, is moved radially in a prescribed reciproal are around the shaft 50,the valve stem 40, is moved up or down positioning the valve portion 28,to direct the flow of liquids into either the chamber 13 or 14, as thecase may be frorn'the container 18.

To operate our dispensing device, the glass 43, is placed in the holder12, as shown in Fig. 1 of the drawings, the glass weight overcoming theaction of the spring 53, provided to maintain the holder 12, 'in theposition shown will impart a slight movement through the walking beamand linkage to slightly move the portion 28, of the valve 8, allowing areduced flow of liquid to enter the glass 43, as the quantity of liquidflowing into the glass 43, increases, its weight increases andproportionately the flow of liquid increases and so on until the valveportion 28, reaches a full open'position and the holder 12, is in avertical position as shown in Fig. 2 of the drawings.

It will be noted when the holder 12, is in a vertical position thewalking beam'49, has been raised on its one end to a position nearlyvertical above the countershaft positioning the slotway 48, of theWalking beam lever at a sharp inclined degree to the vertical link 46,as illustrated in Fig. 2.

When the filled glass 43, is'r'emoved from the holder 12, the spring 53,will return the holder to a rest position as illustrated in Figs. land 5and also the bearinged end end of the link 46, will travel to theopposite end of the walking beam and become engaged in the angular slot54A, as shown in Fig. 1 of the drawings.

In Fig. 6 of the drawings we have illustrated a modified form ofoperating the valve 8, comprising a handle 55, being fastened to acountershaft 56, a crank 57, being fastened centrally within the cavity6, to the countershaft on its one end and being hinged to the link 58,on its other, the link being hinged on its one end to the valve stem 40,associated with the valve 8. It is readily seen that by moving thehandle from one position to another a pouring cycle will be completed.
